Riding-type exerciser

Abstract

A riding-type exerciser includes a base frame and a seat unit having an elongated seat frame with a front portion that extends downwardly from a rear portion thereof and that is mounted pivotally on the base frame adjacent to the front end of the base frame. The seat unit further includes a seat member mounted on the rear portion of the seat frame. An elongated support unit has a bottom portion which is mounted pivotally on the base frame between the front portion of the seat frame and the rear end of the base frame. A pull unit includes an elongated pull beam having a rear portion that is mounted pivotally to the front portion of the seat frame and to a top portion of the support unit, and a handlebar mounted on a front portion of the pull beam. A pedal unit includes a support beam having a lower end mounted pivotally on the base frame adjacent to the front end of the base frame, and a pair of pedal plates mounted on two sides of the support beam. An elongated linking member has a first end connected pivotally to the rear portion of the pull beam and a second end connected pivotally to the support beam. A resistance cylinder has a cylinder body and a piston shaft extending retractably into the cylinder body. The resistance cylinder is mounted pivotally on the base frame adjacent to the rear end of the base frame and on the support unit.

We claim: 
     
       1. A riding-type exerciser, comprising: a base frame having a front end and a rear end;   a seat unit including an elongated seat frame with a rear portion and a front portion that extends downwardly from said rear portion and that has a distal end which is mounted pivotally on said base frame adjacent said front end of said base frame, said seat unit further including a seat member mounted on said rear portion of said seat frame;   an elongated support unit having a top portion and a bottom portion which is mounted pivotally on said base frame between said front portion of said seat frame and said rear end of said base frame;   a pull unit including an elongated pull beam having a front portion and a rear portion that is mounted pivotally to said front portion of said seat frame and to said top portion of said support unit, and a handlebar mounted on said front portion of said pull beam;   a pedal unit including a support beam having a lower end mounted pivotally on said base frame adjacent said front end of said base frame, and a pair of pedal plates mounted on two sides of said support beam;   an elongated linking member having a first end connected pivotally to said rear portion of said pull beam and a second end connected pivotally to said support beam; and   a resistance cylinder having a cylinder body and a piston shaft extending retractably into said cylinder body, one of said cylinder body and said piston shaft being mounted pivotally on said base frame adjacent said rear end of said base frame, the other one of said cylinder body and said piston shaft being mounted pivotally to said support unit.   
     
     
       2. The riding-type exerciser as claimed in claim 1, wherein said seat frame includes a parallel pair of elongated seat posts, said support unit including a parallel pair of elongated support posts, said pull beam of said pull unit extending between said seat posts and between said support posts and being mounted pivotally to said seat posts and said support posts. 
     
     
       3. The riding-type exerciser as claimed in claim 2, wherein said pull beam, said base frame, said seat posts and said support posts cooperatively form a parallel linkage. 
     
     
       4. The riding-type exerciser as claimed in claim 1, further comprising a resilient buffer mounted on said base frame between said front end of said base frame and said front portion of said seat frame. 
     
     
       5. The riding-type exerciser as claimed in claim 1, wherein said support beam has an inclined top end face, said pedal unit further including a resilient buffer secured on said inclined top end face. 
     
     
       6. The riding-type exerciser as claimed in claim 1, wherein said handlebar is mounted pivotally on said front portion of said pull beam, and said pedal plates are mounted pivotally on said support beam. 
     
     
       7. The riding-type exerciser as claimed in claim 1, further comprising a massaging device which includes: a support beam mounted on said rear portion of said seat frame, said support beam having a top end;   a curved connecting bar having top and bottom portions and an intermediate portion which is mounted pivotally on said top end of said support beam; and   two massaging wheel sets, each being mounted rotatably on two sides of said connecting bar at a respective one of said top and bottom portions of said connecting bar.   
     
     
       8. The riding-type exerciser as claimed in claim 7, wherein said massaging device further includes: a mounting tube mounted pivotally on said rear portion of said seat frame, said mounting tube confining a rectangular through-hole therethrough, said support beam being formed as an elongated rectangular beam that extends slidably into said through-hole of said mounting tube;   locking means for locking releasably said support beam to said mounting tube; and   a spring plate formed as an elongated strip which has a first end mounted on said mounting tube and a second end mounted on said rear portion of said seat frame.
